pool_auc function

Calculates the pooled C-statistic (Area Under the ROC Curve) across Multiply Imputed datasets

pool_auc Calculates the pooled C-statistic and 95

by using Rubin's Rules. The C-statistic values are log transformed before pooling.

pool_auc(est_auc, est_se, nimp = 5, log_auc = TRUE)

Arguments

• est_auc: A list of C-statistic (AUC/ROC) values estimated in Multiply Imputed datasets.
• est_se: A list of standard errors of C-statistic values estimated in Multiply Imputed datasets.
• nimp: A numerical scalar. Number of imputed datasets. Default is 5.
• log_auc: If TRUE natural logarithmic transformation is applied before pooling and finally back transformed. If FALSE the raw values are pooled.

Returns

The pooled C-statistic value and the 95
